JIRA - I am looking for archiving options, please

Hello. I am looking for options to archive in JIRA. We have to archive certain issues which contain development info for 5 to 25 years in a format (pdf, html…).

I would prefer a plugin (as an exporter) or a program that picks issues and archives them.

First of all we got the Atlassian documentation that shows you what the program itself can do: https://confluence.atlassian.com/adminjiraserver071/archiving-a-project-802592917.html

And of course our plugin or add-on Project Archiver for JIRA: https://marketplace.atlassian.com/plugins/net.seibertmedia.jira.plugins.project-archiver/server/overview
